【吉光片羽】MVC 导出Word的两种方式

    1.直接将Html转成Word。MVC自带FileResult很好用。Html中我们也可以嵌入自己的样式。

    html:

<div id="target">
    <style>
        table{border-collapse: collapse;border: 1px solid  black;}
        td{border: 1px royalblue solid}
    style>
    <img src="../../Content/eman_sm.png" alt="" />
    <table>
        <tr>
            <td>姓名td>
            <td>成绩td>
        tr>
        <tr>
            <td>张山td>
            <td>80分td>
        tr>
        <tr>
            <td>李四td>
            <td>90分td>
        tr>
    table>
div>
<div style="color: red">div>
<a id="ea" href="#">导出worda>
<a href="@Url.Action("ExportWords")">ExportWordsa>

View Code

get方法会受到url长度的影响，可以换成隐藏的form提交。

<form id="form1" action="/Home/ExportWord">
    <input type="hidden" value=""  name="html" id="cc" />
    <input type="submit" id="st" />
form>
<div id="target">
    <style>
        table{border-collapse: collapse;border: 1px solid  black;}
        td{border: 1px royalblue solid}
    style>
    <table>
        <tr>
            <td>姓名td>
            <td>成绩td>
        tr>
        <tr>
            <td>张山td>
            <td>80分td>
        tr>
        <tr>
            <td>李四td>
            <td>90分td>
        tr>
    table>
div>
<div style="color: red">div>
<a id="ea" href="#">导出worda>
<a href="@Url.Action("ExportWords")">ExportWordsa>
<script>
    $("#ea").click(function () {
        var html = $("#target").html();
        $("#cc").val(html);
        $("#st").click();
    })
script>

View Code

 

Action:

 [ValidateInput(false)]
        public FileResult ExportWord(string html)
        {
            StringBuilder sb = new StringBuilder();
            sb.Append("");
            sb.Append("");
            sb.Append(html);
            sb.Append("");
            var byteArray = System.Text.Encoding.Default.GetBytes(sb.ToString());
            Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
            return File(byteArray, "application/ms-word", "wordtest" + ".doc");
        }

这样的问题是导出的图片是引用型的，路径一变化就不会显示了。优点就是速度很快。

  2.使用Microsoft.Office.Interop.Word 提供的方法创建一个word。

    /// 

        /// 创建一个word
        /// 
        /// 
        public ActionResult ExportWords()
        {
            CreateAWord();
            SetPageHeader("测试创建一个Word文档");
            InsertText("这是一个测试文档的内容", 14, WdColor.wdColorGray10, 1, WdParagraphAlignment.wdAlignParagraphLeft);
            NewLine();
            InsertPicture(@"C:\Users\Administrator\Desktop\duoceshi.png");
            InsertTable();
            SaveWord(@"C:\Users\Administrator\Desktop\\test.doc");
            CloseDocument(@"C:\Users\Administrator\Desktop\\test.doc");
            return null;
        }
        /// 

        /// Word应用对象

        ///

 图片倒是保存住了，可配置的地方很多，速度有些慢，代码量颇多。

 3.如果要导出excel 还是用NPOI最好。 http://www.cnblogs.com/lwme/archive/2011/11/18/npoi_excel_import_export.html

  调用该博主ExcelRender中的方法，返回File。 不然网上的其他办法都很有问题，要么打不开，要么服务器没装office就不行了。

 public FileResult ExportExcel()
        {
            DataTable table = new DataTable();
            table.Columns.Add("aa", typeof(string));
            table.Columns.Add("bb", typeof(string));
            table.Columns.Add("cc", typeof(string));
            for (int i = 0; i < 10; i++)
            {
                string a = DateTime.Now.Ticks.ToString();
                Thread.Sleep(1);
                string b = DateTime.Now.Ticks.ToString();
                Thread.Sleep(1);
                string c = DateTime.Now.Ticks.ToString();
                Thread.Sleep(1);
                table.Rows.Add(a, b, c);
            }

           var ms= ExcelRender.RenderToExcel(table);

            return File(ms, "application/vnd.ms-excel", "考试成绩.xls");
        }

 4. Excel导入。

  file就是一个HttpPostedFileBase 对象。即上传的excel文件。用ExcelRender 转换为table 再进行插入数据库的操作。

   byte[] filebBytes =new byte[file.ContentLength];
   file.InputStream.Read(filebBytes, 0, file.ContentLength);

   var table = ExcelRender.RenderFromExcel(new MemoryStream(filebBytes),0,0);
